ABSTRACT

Compounds of the formula (I), in which R 1 , R 2 , R 3a , R 3b , R 3c  and R 3d  have the meanings indicated in claim 1, are inhibitors of tyrosine kinases, in particular Met kinase, and can be employed, inter alia, for the treatment of tumours.

BACKGROUND OF THE INVENTION

The invention had the object of finding novel compounds having valuableproperties, in particular those which can be used for the preparation ofmedicaments.

The present invention relates to compounds and to the use of compoundsin which the inhibition, regulation and/or modulation of signaltransduction by kinases, in particular tyrosine kinases and/orserine/threonine kinases, plays a role, furthermore to pharmaceuticalcompositions which comprise these compounds, and to the use of thecompounds for the treatment of kinase-induced diseases.

In particular, the present invention relates to compounds and to the useof compounds in which the inhibition, regulation and/or modulation ofsignal transduction by Met kinase plays a role.

One of the principal mechanisms by which cellular regulation is effectedis through the transduction of extracellular signals across the membranethat in turn modulate biochemical pathways within the cell. Proteinphosphorylation represents one course by which intracellular signals arepropagated from molecule to molecule resulting finally in a cellularresponse. These signal transduction cascades are highly regulated andoften overlap, as is evident from the existence of many protein kinasesas well as phosphatases. Phosphorylation of proteins occurspredominantly at serine, threonine or tyrosine residues, and proteinkinases have therefore been classified by their specificity ofphosphorylation site, i.e. serine/threonine kinases and tyrosinekinases. Since phosphorylation is such a ubiquitous process within cellsand since cellular phenotypes are largely influenced by the activity ofthese pathways, it is currently believed that a number of disease statesand/or diseases are attributable to either aberrant activation orfunctional mutations in the molecular components of kinase cascades.Consequently, considerable attention has been devoted to thecharacterisation of these proteins and compounds that are able tomodulate their activity (for a review see: Weinstein-Oppenheimer et al.Pharma. & Therap., 2000, 88, 229-279).

The role of the receptor tyrosine kinase Met in human oncogenesis andthe possibility of inhibition of HGF (hepatocyte growth factor)dependent Met activation are described by S. Berthou et al. in Oncogene,Vol. 23, No. 31, pages 5387-5393 (2004). The inhibitor SU11274 describedtherein, a pyrrole-indoline compound, is potentially suitable forcombating cancer. Another Met kinase inhibitor for cancer therapy isdescribed by J. G. Christensen et al. in Cancer Res. 2003, 63(21),7345-55.

A further tyrosine kinase inhibitor for combating cancer is reported byH. Hov et al. in Clinical Cancer Research Vol. 10, 6686-6694 (2004). Thecompound PHA-665752, an indole derivative, is directed against the HGFreceptor c-Met. It is furthermore reported therein that HGF and Met makea considerable contribution to the malignant process of various forms ofcancer, such as, for example, multiple myeloma.

The synthesis of small compounds which specifically inhibit, regulateand/or modulate signal transduction by tyrosine kinases and/orserine/threonine kinases, in particular Met kinase, is thereforedesirable and an aim of the present invention.

It has been found that the compounds according to the invention andsalts thereof have very valuable pharmacological properties while beingwell tolerated.

The present invention specifically relates to compounds of the formula Iwhich inhibit, regulate and/or modulate signal transduction by Metkinase, to compositions which comprise these compounds, and to processesfor the use thereof for the treatment of Met kinase-induced diseases andcomplaints, such as angiogenesis, cancer, tumour formation, growth andpropagation, arteriosclerosis, ocular diseases, such as age-inducedmacular degeneration, choroidal neovascularisation and diabeticretinopathy, inflammatory diseases, arthritis, thrombosis, fibrosis,glomerulonephritis, neurodegeneration, psoriasis, restenosis, woundhealing, trans-plant rejection, metabolic diseases and diseases of theimmune system, also autoimmune diseases, cirrhosis, diabetes anddiseases of the blood vessels, also instability and permeability and thelike in mammals.

Solid tumours, in particular fast-growing tumours, can be treated withMet kinase inhibitors. These solid tumours include monocytic leukaemia,brain, urogenital, lymphatic system, stomach, laryngeal and lungcarcinoma, including lung adenocarcinoma and small-cell lung carcinoma.

The present invention is directed to processes for the regulation,modulation or inhibition of Met kinase for the prevention and/ortreatment of diseases in connection with unregulated or disturbed Metkinase activity. In particular, the compounds of the formula I can alsobe employed in the treatment of certain forms of cancer. The compoundsof the formula I can furthermore be used to provide additive orsynergistic effects in certain existing cancer chemotherapies, and/orcan be used to restore the efficacy of certain existing cancerchemotherapies and radiotherapies.

The compounds of the formula I can furthermore be used for the isolationand investigation of the activity or expression of Met kinase. Inaddition, they are particularly suitable for use in diagnostic methodsfor diseases in connection with unregulated or disturbed Met kinaseactivity.

It can be shown that the compounds according to the invention have anantiproliferative action in vivo in a xenotransplant tumour model. Thecompounds according to the invention are administered to a patienthaving a hyperproliferative disease, for example to inhibit tumourgrowth, to reduce inflammation associated with a lymphoproliferativedisease, to inhibit transplant rejection or neurological damage due totissue repair, etc. The present compounds are suitable for prophylacticor therapeutic purposes. As used herein, the term “treatment” is used torefer to both prevention of diseases and treatment of pre-existingconditions. The prevention of proliferation is achieved byadministration of the compounds according to the invention prior to thedevelopment of overt disease, for example to prevent the growth oftumours, prevent metastatic growth, diminish restenosis associated withcardiovascular surgery, etc. Alternatively, the compounds are used forthe treatment of ongoing diseases by stabilising or improving theclinical symptoms of the patient.

The host or patient can belong to any mammalian species, for example aprimate species, particularly humans; rodents, including mice, rats andhamsters; rabbits; horses, cows, dogs, cats, etc. Animal models are ofinterest for experimental investigations, providing a model fortreatment of human disease.

The susceptibility of a particular cell to treatment with the compoundsaccording to the invention can be determined by in vitro tests.Typically, a culture of the cell is combined with a compound accordingto the invention at various concentrations for a periodine of time whichis sufficient to allow the active agents to induce cell death or toinhibit migration, usually between about one hour and one week. In vitrotesting can be carried out using cultivated cells from a biopsy sample.The viable cells remaining after the treatment are then counted.

The dose varies depending on the specific compound used, the specificdisease, the patient status, etc. A therapeutic dose is typicallysufficient considerably to reduce the undesired cell population in thetarget tissue while the viability of the patient is maintained. Thetreatment is generally continued until a considerable reduction hasoccurred, for example an at least about 50% reduction in the cellburden, and may be continued until essentially no more undesired cellsare detected in the body.

For identification of a signal transduction pathway and for detection ofinteractions between various signal transduction pathways, variousscientists have developed suitable models or model systems, for examplecell culture models (for example Khwaja et al., EMBO, 1997, 16, 2783-93)and models of transgenic animals (for example White et al., Oncogene,2001, 20, 7064-7072). For the determination of certain stages in thesignal transduction cascade, interacting compounds can be utilised inorder to modulate the signal (for example Stephens et al., BiochemicalJ., 2000, 351, 95-105). The compounds according to the invention canalso be used as reagents for testing kinase-dependent signaltransduction pathways in animals and/or cell culture models or in theclinical diseases mentioned in this application.

Measurement of the kinase activity is a technique which is well known tothe person skilled in the art. Generic test systems for thedetermination of the kinase activity using substrates, for examplehistone (for example Alessi et al., FEBS Lett. 1996, 399, 3, pages333-338) or the basic myelin protein, are described in the literature(for example Campos-González, R. and Glenney, Jr., J. R. 1992, J. Biol.Chem. 267, page 14535).

For the identification of kinase inhibitors, various assay systems areavailable. In scintillation proximity assay (Sorg et al., J. of.Biomolecular Screening, 2002, 7, 11-19) and flashplate assay, theradioactive phosphorylation of a protein or peptide as substrate withγATP is measured. In the presence of an inhibitory compound, a decreasedradioactive signal, or none at all, is detectable. Furthermore,homogeneous time-resolved fluorescence resonance energy transfer(HTR-FRET) and fluorescence polarisation (FP) technologies are suitableas assay methods (Sills et al., J. of Biomolecular Screening, 2002,191-214).

Other non-radioactive ELISA assay methods use specificphospho-antibodies (phospho-ABs). The phospho-AB binds only thephosphorylated substrate. This binding can be detected bychemiluminescence using a second peroxidase-conjugated anti-sheepantibody (Ross et al., 2002, Biochem. J.).

There are many diseases associated with deregulation of cellularproliferation and cell death (apoptosis). The conditions of interestinclude, but are not limited to, the following. The compounds accordingto the invention are suitable for the treatment of various conditionswhere there is proliferation and/or migration of smooth muscle cellsand/or inflammatory cells into the intimal layer of a vessel, resultingin restricted blood flow through that vessel, for example in the case ofneointimal occlusive lesions. Occlusive graft vascular diseases ofinterest include atherosclerosis, coronary vascular disease aftergrafting, vein graft stenosis, peri-anastomatic prosthetic restenosis,restenosis after angioplasty or stent placement, and the like.

The said compounds according to the invention can be used in their finalnon-salt form. On the other hand, the present invention also encompassesthe use of these compounds in the form of their pharmaceuticallyacceptable salts, which can be derived from various organic andinorganic acids and bases by procedures known in the art.Pharmaceutically acceptable salt forms of the compounds of the formula Iare for the most part prepared by conventional methods. If the compoundof the formula I contains a carboxyl group, one of its suitable saltscan be formed by reacting the compound with a suitable base to give thecorresponding base-addition salt. Such bases are, for example, alkalimetal hydroxides, including potassium hydroxide, sodium hydroxide andlithium hydroxide; alkaline-earth metal hydroxides, such as bariumhydroxide and calcium hydroxide; alkali metal alkoxides, for examplepotassium ethoxide and sodium propoxide; and various organic bases, suchas piperidine, diethanolamine and N-methylglutamine. The aluminium saltsof the compounds of the formula I are likewise included. In the case ofcertain compounds of the formula I, acid-addition salts can be formed bytreating these compounds with pharmaceutically acceptable organic andinorganic acids, for example hydrogen halides, such as hydrogenchloride, hydrogen bromide or hydrogen iodide, other mineral acids andcorresponding salts thereof, such as sulfate, nitrate or phosphate andthe like, and alkyl- and monoarylsulfonates, such as ethanesulfonate,toluenesulfonate and benzenesulfonate, and other organic acids andcorresponding salts thereof, such as acetate, trifluoroacetate,tartrate, maleate, succinate, citrate, benzoate, salicylate, ascorbateand the like. Accordingly, pharmaceutically acceptable acid-additionsalts of the compounds of the formula I include the following: acetate,adipate, alginate, arginate, aspartate, benzoate, benzenesulfonate(besylate), bisulfate, bisulfite, bromide, butyrate, camphorate,camphorsulfonate, caprylate, chloride, chlorobenzoate, citrate,cyclopentanepropionate, digluconate, dihydrogenphosphate,dinitrobenzoate, dodecylsulfate, ethanesulfonate, fumarate, galacterate(from mucic acid), galacturonate, glucoheptanoate, gluconate, glutamate,glycerophosphate, hemisuccinate, hemisulfate, heptanoate, hexanoate,hippurate, hydrochloride, hydrobromide, hydroiodide,2-hydroxyethanesulfonate, iodide, isethionate, isobutyrate, lactate,lactobionate, malate, maleate, malonate, mandelate, metaphosphate,methanesulfonate, methylbenzoate, monohydrogenphosphate,2-naphthalenesulfonate, nicotinate, nitrate, oxalate, oleate, palmoate,pectinate, persulfate, phenylacetate, 3-phenylpropionate, phosphate,phosphonate, phthalate, but this does not represent a restriction.

Furthermore, the base salts of the compounds according to the inventioninclude aluminium, ammonium, calcium, copper, iron(III), iron(II),lithium, magnesium, manganese(III), manganese(II), potassium, sodium andzinc salts, but this is not intended to represent a restriction. Of theabove-mentioned salts, preference is given to ammonium; the alkali metalsalts sodium and potassium, and the alkaline-earth metal salts calciumand magnesium. Salts of the compounds of the formula I which are derivedfrom pharmaceutically acceptable organic non-toxic bases include saltsof primary, secondary and tertiary amines, substituted amines, alsoincluding naturally occurring substituted amines, cyclic amines, andbasic ion exchanger resins, for example arginine, betaine, caffeine,chloroprocaine, choline, N,N′-dibenzylethylenediamine (benzathine),dicyclohexylamine, diethanolamine, diethylamine, 2-diethylaminoethanol,2-dimethylaminoethanol, ethanolamine, ethylenediamine,N-ethylmorpholine, N-ethylpiperidine, glucamine, glucosamine, histidine,hydrabamine, isopropylamine, lidocaine, lysine, meglumine,N-methyl-D-glucamine, morpholine, piperazine, piperidine, polyamineresins, procaine, purines, theobromine, triethanolamine, triethylamine,trimethylamine, tripropylamine and tris(hydroxymethyl)methylamine(tromethamine), but this is not intended to represent a restriction.

The acid-addition salts of basic compounds of the formula I are preparedby bringing the free base form into contact with a sufficient amount ofthe desired acid, causing the formation of the salt in a conventionalmanner. The free base can be regenerated by bringing the salt form intocontact with a base and isolating the free base in a conventionalmanner. The free base forms differ in a certain respect from thecorresponding salt forms thereof with respect to certain physicalproperties, such as solubility in polar solvents; for the purposes ofthe invention, however, the salts otherwise correspond to the respectivefree base forms thereof.

As mentioned, the pharmaceutically acceptable base-addition salts of thecompounds of the formula I are formed with metals or amines, such asalkali metals and alkaline-earth metals or organic amines. Preferredmetals are sodium, potassium, magnesium and calcium. Preferred organicamines are N,N′-dibenzylethylenediamine, chloroprocaine, choline,diethanolamine, ethylenediamine, N-methyl-D-glucamine and procaine.

The base-addition salts of acidic compounds according to the inventionare prepared by bringing the free acid form into contact with asufficient amount of the desired base, causing the formation of the saltin a conventional manner. The free acid can be regenerated by bringingthe salt form into contact with an acid and isolating the free acid in aconventional manner. The free acid forms differ in a certain respectfrom the corresponding salt forms thereof with respect to certainphysical properties, such as solubility in polar solvents; for thepurposes of the invention, however, the salts otherwise correspond tothe respective free acid forms thereof.

If a compound according to the invention contains more than one groupwhich is capable of forming pharmaceutically acceptable salts of thistype, the invention also encompasses multiple salts. Typical multiplesalt forms include, for example, bitartrate, diacetate, difumarate,dimeglumine, diphosphate, disodium and trihydrochloride, but this is notintended to represent a restriction.

With regard to that stated above, it can be seen that the expression“pharmaceutically acceptable salt” in the present connection is taken tomean an active ingredient which comprises a compound of the formula I inthe form of one of its salts, in particular if this salt form impartsimproved pharmacokinetic properties on the active ingredient comparedwith the free form of the active ingredient or any other salt form ofthe active ingredient used earlier. The pharmaceutically acceptable saltform of the active ingredient can also provide this active ingredientfor the first time with a desired pharmacokinetic property which it didnot have earlier and can even have a positive influence on thepharmacodynamics of this active ingredient with respect to itstherapeutic efficacy in the body.

The invention furthermore relates to medicaments comprising at least onecompound of the formula I and/or pharmaceutically usable derivatives,solvates and stereoisomers thereof, including mixtures thereof in allratios, and optionally excipients and/or adjuvants.

Pharmaceutical formulations can be administered in the form of dosageunits which comprise a predetermined amount of active ingredient perdosage unit. Such a unit can comprise, for example, 0.5 mg to 1 g,preferably 1 mg to 700 mg, particularly preferably 5 mg to 100 my, of acompound according to the invention, depending on the condition treated,the method of administration and the age, weight and condition of thepatient, or pharmaceutical formulations can be administered in the formof dosage units which comprise a predetermined amount of activeingredient per dosage unit. Preferred dosage unit formulations are thosewhich comprise a daily dose or part-dose, as indicated above, or acorresponding fraction thereof of an active ingredient. Furthermore,pharmaceutical formulations of this type can be prepared using a processwhich is generally known in the pharmaceutical art.

Pharmaceutical formulations can be adapted for administration via anydesired suitable method, for example by oral (including buccal orsublingual), rectal, nasal, topical (including buccal, sublingual ortransdermal), vaginal or parenteral (including subcutaneous,intramuscular, intravenous or intradermal) methods. Such formulationscan be prepared using all processes known in the pharmaceutical art by,for example, combining the active ingredient with the excipient(s) oradjuvant(s).

Pharmaceutical formulations adapted for oral administration can beadministered as separate units, such as, for example, capsules ortablets; powders or granules; solutions or suspensions in aqueous ornon-aqueous liquids; edible foams or foam foods; or oil-in-water liquidemulsions or water-in-oil liquid emulsions.

Thus, for example, in the case of oral administration in the form of atablet or capsule, the active-ingredient component can be combined withan oral, non-toxic and pharmaceutically acceptable inert excipient, suchas, for example, ethanol, glycerol, water and the like. Powders areprepared by comminuting the compound to a suitable fine size and mixingit with a pharmaceutical excipient comminuted in a similar manner, suchas, for example, an edible carbohydrate, such as, for example, starch ormannitol. A flavour, preservative, dispersant and dye may likewise bepresent.

Capsules are produced by preparing a powder mixture as described aboveand filling shaped gelatine shells therewith. Glidants and lubricants,such as, for example, highly disperse silicic acid, talc, magnesiumstearate, calcium stearate or polyethylene glycol in solid form, can beadded to the powder mixture before the filling operation. A disintegrantor solubiliser, such as, for example, agar-agar, calcium carbonate orsodium carbonate, may likewise be added in order to improve theavailability of the medicament after the capsule has been taken.

In addition, if desired or necessary, suitable binders, lubricants anddisintegrants as well as dyes can likewise be incorporated into themixture. Suitable binders include starch, gelatine, natural sugars, suchas, for example, glucose or beta-lactose, sweeteners made from maize,natural and synthetic rubber, such as, for example, acacia, tragacanthor sodium alginate, carboxymethylcellulose, polyethylene glycol, waxes,and the like. The lubricants used in these dosage forms include sodiumoleate, sodium stearate, magnesium stearate, sodium benzoate, sodiumacetate, sodium chloride and the like. The disintegrants include,without being restricted thereto, starch, methylcellulose, agar,bentonite, xanthan gum and the like. The tablets are formulated by, forexample, preparing a powder mixture, granulating or dry-pressing themixture, adding a lubricant and a disintegrant and pressing the entiremixture to give tablets. A powder mixture is prepared by mixing thecompound comminuted in a suitable manner with a diluent or a base, asdescribed above, and optionally with a binder, such as, for example,carboxymethylcellulose, an alginate, gelatine or polyvinylpyrrolidone, adissolution retardant, such as, for example, paraffin, an absorptionaccelerator, such as, for example, a quaternary salt, and/or anabsorbent, such as, for example, bentonite, kaolin or dicalciumphosphate. The powder mixture can be granulated by wetting it with abinder, such as, for example, syrup, starch paste, acadia mucilage orsolutions of cellulose or polymer materials and pressing it through asieve. As an alternative to granulation, the powder mixture can be runthrough a tabletting machine, giving lumps of non-uniform shape, whichare broken up to form granules. The granules can be lubricated byaddition of stearic acid, a stearate salt, talc or mineral oil in orderto prevent sticking to the tablet casting moulds. The lubricated mixtureis then pressed to give tablets. The compounds according to theinvention can also be combined with a free-flowing inert excipient andthen pressed directly to give tablets without carrying out thegranulation or dry-pressing steps. A transparent or opaque protectivelayer consisting of a shellac sealing layer, a layer of sugar or polymermaterial and a gloss layer of wax may be present. Dyes can be added tothese coatings in order to be able to differentiate between differentdosage units.

Oral liquids, such as, for example, solution, syrups and elixirs, can beprepared in the form of dosage units so that a given quantity comprisesa pre-specified amount of the compound. Syrups can be prepared bydissolving the compound in an aqueous solution with a suitable flavour,while elixirs are prepared using a non-toxic alcoholic vehicle.Suspensions can be formulated by dispersion of the compound in anon-toxic vehicle. Solubilisers and emulsifiers, such as, for example,ethoxylated isostearyl alcohols and polyoxyethylene sorbitol ethers,preservatives, flavour additives, such as, for example, peppermint oilor natural sweeteners or saccharin, or other artificial sweeteners andthe like, can likewise be added.

The dosage unit formulations for oral administration can, if desired, beencapsulated in microcapsules. The formulation can also be prepared insuch a way that the release is extended or retarded, such as, forexample, by coating or embedding of particulate material in polymers,wax and the like.

The compounds of the formula I and salts, solvates and physiologicallyfunctional derivatives thereof can also be administered in the form ofliposome delivery systems, such as, for example, small unilamellarvesicles, large unilamellar vesicles and multilamellar vesicles.Liposomes can be formed from various phospholipids, such as, forexample, cholesterol, stearylamine or phosphatidylcholines.

The compounds of the formula I and the salts, solvates andphysiologically functional derivatives thereof can also be deliveredusing monoclonal antibodies as individual carriers to which the compoundmolecules are coupled. The compounds can also be coupled to solublepolymers as targeted medicament carriers. Such polymers may encompasspolyvinylpyrrolidone, pyran copolymer,polyhydroxypropylmethacrylamidophenol, polyhydroxyethylaspartamidophenolor polyethylene oxide polylysine, substituted by palmitoyl radicals. Thecompounds may furthermore be coupled to a class of biodegradablepolymers which are suitable for achieving controlled release of amedicament, for example polylactic acid, poly-epsilon-caprolactone,polyhydroxybutyric acid, polyorthoesters, polyacetals,polydihydroxypyrans, polycyanoacrylates and crosslinked or amphipathicblock copolymers of hydrogels.

Pharmaceutical formulations adapted for transdermal administration canbe administered as independent plasters for extended, close contact withthe epidermis of the recipient. Thus, for example, the active ingredientcan be delivered from the plaster by iontophoresis, as described ingeneral terms in Pharmaceutical Research, 3(6), 318 (1986).

Pharmaceutical compounds adapted for topical administration can beformulated as ointments, creams, suspensions, lotions, powders,solutions, pastes, gels, sprays, aerosols or oils.

For the treatment of the eye or other external tissue, for example mouthand skin, the formulations are preferably applied as topical ointment orcream. In the case of formulation to give an ointment, the activeingredient can be employed either with a paraffinic or a water-misciblecream base. Alternatively, the active ingredient can be formulated togive a cream with an oil-in-water cream base or a water-in-oil base.

Pharmaceutical formulations adapted for topical application to the eyeinclude eye drops, in which the active ingredient is dissolved orsuspended in a suitable carrier, in particular an aqueous solvent.

Pharmaceutical formulations adapted for topical application in the mouthencompass lozenges, pastilles and mouthwashes.

Pharmaceutical formulations adapted for rectal administration can beadministered in the form of suppositories or enemas.

Pharmaceutical formulations adapted for nasal administration in whichthe carrier substance is a solid comprise a coarse powder having aparticle size, for example, in the range 20-500 microns, which isadministered in the manner in which snuff is taken, i.e. by rapidinhalation via the nasal passages from a container containing the powderheld close to the nose. Suitable formulations for administration asnasal spray or nose drops with a liquid as carrier substance encompassactive-ingredient solutions in water or oil.

Pharmaceutical formulations adapted for administration by inhalationencompass finely particulate dusts or mists, which can be generated byvarious types of pressurised dispensers with aerosols, nebulisers orinsufflators.

Pharmaceutical formulations adapted for vaginal administration can beadministered as pessaries, tampons, creams, gels, pastes, foams or sprayformulations.

Pharmaceutical formulations adapted for parenteral administrationinclude aqueous and non-aqueous sterile injection solutions comprisingantioxidants, buffers, bacteriostatics and solutes, by means of whichthe formulation is rendered isotonic with the blood of the recipient tobe treated; and aqueous and non-aqueous sterile suspensions, which maycomprise suspension media and thickeners. The formulations can beadministered in single-dose or multidose containers, for example sealedampoules and vials, and stored in freeze-dried (lyophilised) state, sothat only the addition of the sterile carrier liquid, for example waterfor injection purposes, immediately before use is necessary. Injectionsolutions and suspensions pre-pared in accordance with the recipe can beprepared from sterile powders, granules and tablets.

It goes without saying that, in addition to the above particularlymentioned constituents, the formulations may also comprise other agentsusual in the art with respect to the particular type of formulation;thus, for example, formulations which are suitable for oraladministration may comprise flavours.

A therapeutically effective amount of a compound of the formula Idepends on a number of factors, including, for example, the age andweight of the animal, the precise condition that requires treatment, andits severity, the nature of the formulation and the method ofadministration, and is ultimately determined by the treating doctor orvet. However, an effective amount of a compound according to theinvention for the treatment of neoplastic growth, for example colon orbreast carcinoma, is generally in the range from 0.1 to 100 mg/kg ofbody weight of the recipient (mammal) per day and particularly typicallyin the range from 1 to 10 mg/kg of body weight per day. Thus, the actualamount per day for an adult mammal weighing 70 kg is usually between 70and 700 mg, where this amount can be administered as a single dose perday or usually in a series of part-doses (such as, for example, two,three, four, five or six) per day, so that the total daily dose is thesame. An effective amount of a salt or solvate or of a physiologicallyfunctional derivative thereof can be determined as the fraction of theeffective amount of the compound according to the invention per se. Itcan be assumed that similar doses are suitable for the treatment ofother conditions mentioned above.

The invention furthermore relates to medicaments comprising at least onecompound of the formula I and/or pharmaceutically usable derivatives,solvates and stereoisomers thereof, including mixtures thereof in allratios, and at least one further medicament active ingredient.

Assays

The compounds of the formula I described in the examples were tested bythe assays described below and were found to have kinase inhibitoryactivity. Other assays are known from the literature and could readilybe performed by the person skilled in the art (see, for example,Dhanabal et al., Cancer Res. 59:189-197; Xin et al., J. Biol. Chem.274:9116-9121; Sheu et al., Anticancer Res. 18:4435-4441; Ausprunk etal., Dev. Biol. 38:237-248; Gimbrone et al., J. Natl. Cancer Inst.52:413-427; Nicosia et al., In Vitro 18:538-549).

Measurement of Met Kinase Activity

According to the manufacturer's data (Met, active, upstate, catalogueNo. 14-526), Met kinase is expressed for the purposes of proteinproduction in insect cells (Sf21; S. frugiperda) and subsequentaffinity-chromatographic purification as “N-terminal 6His-tagged”recombinant human protein in a baculovirus expression vector.

The kinase activity can be measured using various available measurementsystems. In the scintillation proximity method (Sorg et al., J. ofBiomolecular Screening, 2002, 7, 11-19), the flashplate method or thefilter binding test, the radioactive phosphorylation of a protein orpeptide as substrate is measured using radioactively labelled ATP(³²P-ATP, ³³P-ATP). In the case of the presence of an inhibitorycompound, a reduced radioactive signal, or none at all, can be detected.Furthermore, homogeneous time-resolved fluorescence resonance energytransfer (HTR-FRET) and fluoroescence polarisation (FP) technologies canbe used as assay methods (Sills et al., J. of Biomolecular Screening,2002, 191-214).

Other non-radioactive ELISA assay methods use specificphospho-antibodies (phospho-ABs). The phospho-antibody only binds thephosphorylated substrate. This binding can be detected bychemiluminescence using a second peroxidase-conjugated antibody (Ross etal., 2002, Biochem. J.).

Flashplate Method (Met Kinase)

The test plates used are 96-well Flashplate^(R) microtitre plates fromPerkin Elmer (Cat. No. SM P200). The components of the kinase reactiondescribed below are pipetted into the assay plate. The Met kinase andthe substrate poly Ala-Glu-Lys-Tyr, (pAGLT, 6:2:5:1), are incubated for3 hrs at room temperature with radioactively labelled ³³P-ATP in thepresence and absence of test substances in a total volume of 100 μl. Thereaction is terminated using 150 μl of a 60 mM EDTA solution. Afterincubation for a further 30 min at room temperature, the supernatantsare filtered off with suction, and the wells are washed three times with200 μl of 0.9% NaCl solution each time. The measurement of the boundradioactivity is carried out by means of a scintillation measuringinstrument (Topcount NXT, Perkin-Elmer).

The full value used is the inhibitor-free kinase reaction. This shouldbe approximately in the range 6000-9000 cpm. The pharmacological zerovalue used is staurosporin in a final concentration of 0.1 mM. Theinhibitory values (IC50) are determined using the RS1_MTS program.
